Description
Technical field
The present invention relates to a kind of cooling unit that comprises pump, make blades installation on pump shaft.
Background technique
Coolant pump in Motor Vehicle is generally used for controlling the coolant flow with cooling internal combustion engines, and wherein the transfer rate of this coolant pump regulates with the function of cooling requirement.Therefore, particularly, during the cold start-up stage of internal-combustion engine, not only do not need cooling, even can not expect, because it has extended the cold start-up stage, and because it has extended the cryogenic treatment stage, and because this has produced the fuel consumption improving, and pollutant emission.The valve that the adjusting of the transfer rate of coolant pump or control trigger by electromagnetism conventionally in this case or the valve of connector or other types carry out.
Be known that the coolant pump with adjustable slideway, in order to regulate the transfer rate of pump, these coolant pumps can slide above the impeller of pump simultaneously.The adjusting of slideway is undertaken by piston-cylinder unit in this case, and the secondary pump wherein the pressure utilization of piston being positioned on pump shaft in addition produces.If slideway is opened in this process, the impeller of pump freely, therefore, conventionally open similarly by secondary pump intake and the bypass tube of exerting pressure between side.Thus, the impeller of secondary pump significantly rotation of isostasy ground in cooling liquid.Yet if valve closes, the impeller of secondary pump can be exerted pressure and be driven thus slideway.Because pump directly passes through internal combustion engine drive, particularly by the internal combustion engine drive in Motor Vehicle, must make described pump in all speed range inner conversions, this is problematic really in the low engine speed range of idle running, because the impeller of secondary pump can only apply little pressure in this case.Even under the high rotating speed of the impeller of secondary pump, no matter whether bypass tube passage is opened, also can there is following situation: the impeller of secondary pump applies slight pressure, in the worst case, even can drive slideway, reduce thus the transfer rate of pump, particularly, when high rotating speed, the output of internal-combustion engine has extremely damaged the latter thus.
Summary of the invention
Therefore, the invention solves the problem that cooling unit is provided to the mode of execution of improvement, it can reliable and conversion exactly in all possible speed range.
According to the present invention, this problem solves by the theme of independent claims.Favourable mode of execution is the theme of dependent claims.
The present invention is based on the overall thought of the logical valve of the current 3/2-of providing conventional logical valve of 2/2-before replacing, and the transfer rate of the pump by described valve control cooling unit, be used in particular for the transfer rate of pump of the cooling unit of internal combustion engine of motor vehicle.At this, described in comprising, cooling unit is incorporated to the pump of cooling circuit, and for example coolant pump, has the impeller being arranged on pump shaft, and adjustable slideway, and described adjustable slideway can slide on impeller, thereby regulates the transfer rate of pump.Secondary pump is similarly arranged on described pump shaft, for applying the hydrodynamic pressure that regulates slideway.Utilization is according to the logical valve of 3/2-of the present invention, at the logical valve of this 3/2-of primary importance place, close the side of exerting pressure of secondary pump, and make to absorb side and be connected with cooling circuit, and at the logical valve of this 3/2-of second place place, the side of exerting pressure of secondary pump is connected with slideway, the suction side of secondary pump is connected with cooling circuit, nowadays can get rid of following situation: under high rotating speed, and no matter by-pass line is opened, the impeller of secondary pump applies slight pressure, and regulating whereby slideway, this will cause cooling interruption or cause the transfer rate of the pump of cooling liquid obviously to reduce.In order to prevent this phenomenon, exerting pressure of secondary pump, between side and the logical valve of 3/2-, provide reduction valve, when reaching predetermined pressure, this reduction valve is opened in cooling circuit direction.Under the high rotating speed of the high rotating speed of pump and the impeller of secondary pump, the side of exerting pressure of secondary pump is closed thus, the reduction valve that is wherein arranged in secondary pump downstream has guaranteed that the fuel pressure of exerting pressure in side of secondary pump can not become higher than the pressure in cooling circuit self on the one hand, and guaranteed on the other hand at least to exist from the pressure of cooling circuit always, can realize fast driving slideway thus.In this case, the suction side of secondary pump is similarly connected with slideway, thus, on described slideway, produces vacuum, makes described slideway securely fixing thus.By the vacuum existing on slideway, the opening of slideway is also supported, and this is also favourable for quick variation circulation.Yet when slideway is closed, while sliding on the impeller of pump, the side of exerting pressure of secondary pump is first connected with slideway, and the suction side of secondary pump and the connection between slideway are interrupted.The suction side of the secondary pump in this transition state still has close contact with cooling circuit.By applying vacuum to slideway, slideway can maneuverable especially mode design, for example, have the Sealing of the operation of being significantly easier to and/or for example can save resetting spring completely.
Obviously, the hydrodynamic pressure of secondary pump in this case does not directly work to slideway conventionally, but annular piston is worked, and this annular piston adjustable ground is arranged in annular space, and connects with slideway.Yet; the vacuum that the slideway at the primary importance place of secondary pump is worked can not only can be given annular piston or further more easily operation of slideway by whole omission because of for example Sealing; and in first of the logical valve of the 3/2-vacuum that slideway or annular piston are worked of shifting one's position, can be used as other inefficacy-protection mechanism, this support or even substitute existing resetting spring.Reduction valve in this case can be designed to the valve that spring preloads, or with for example on annular piston the mode without Sealing design, may produce certain leakage thus, this prevents following situation: when slideway is closed, impeller by secondary pump does not produce too high malleation, because due to the leakage possibility that Sealing disappearance causes, the plussage of leakage is back in cooling circuit.By means of cooling unit according to the present invention, can realize thus the easy operating of pump and the accurately operation of conversion, irrelevant with the rotating speed of pump shaft.
In this case, according to cooling unit of the present invention, can shorten the cold start-up period of internal-combustion engine, internal-combustion engine heating more quickly thus, thus the contaminativity producing discharge reduces.During the cold start-up period of internal-combustion engine, the side of exerting pressure of suction side and secondary pump disconnects, the hydrodynamic pressure that secondary pump can be applied make slideway be adjusted to its operating position.In the cold start-up period, increase, accelerate in the situation of heating process of internal-combustion engine, can make the link enhancement of exerting pressure between side and suction side of secondary pump, and significantly reduce thus the hydrodynamic pressure that secondary pump produces, slideway regulates and self enters its open position during this period, and make the impeller of pump free, and make pump cooling liquid can be delivered to internal-combustion engine, make internal-combustion engine cooling.
According in another favourable development of the present invention program, said pump comprises annular piston, and this annular piston is adjustable in annular space, and connects with slideway.Now, annular piston seals with respect to annular space by the axis Sealing of axial direction and the radial seal of radial direction.By applying malleation, in the case, annular piston and regulate slideway via annular piston above impeller, wherein for example can be by suitable spring, supported or carry out in addition the reverse adjusting of slideway by annular piston being applied to vacuum, thus, annular piston is retracted.By provide Sealing between annular piston and annular space, do not have fluid passage herein, yet in pure theory, these Sealings also can omit, make annular space for example as reduction valve.In the case, the leakage producing through annular space is back to cooling circuit, wherein according to this mode of execution, even if slideway is closed, impeller by secondary pump can not produce too high malleation, because stoped this malleation through the lasting leakage of annular space.In pure theory, in this embodiment, can omit other reduction valve completely, not only can save Sealing thus, also can save reduction valve itself.
Equally easily expect, gone out outside the reagent pump impeller of pump, the impeller of secondary pump can produce pressure, thus support body pump, and wherein, if for example pressure-limit valve of reduction valve mode is provided, this is also possible.
Other key character of the present invention and advantage are obtained by dependent claims, accompanying drawing and the explanation of relevant drawings by reference to the accompanying drawings.
Be understood that above-mentioned feature and below the feature of explaining can not only be used with above-mentioned each assembled state, can also use with other combination or difference self, and not deviate from scope of the present invention.

Embodiment
According to Fig. 1 and Fig. 2, according to cooling unit 1 of the present invention, be used in particular for the cooling circuit of internal combustion engines in motor vehicles, comprise the pump 2 being incorporated in cooling circuit 8, in this situation, pump 2 is designed to coolant pump.Pump 2 comprises the impeller 4 being arranged on pump shaft 3, and adjustable slideway 5, and this slideway 5 can slide above impeller 4, and the transfer rate of control pump 2 thus.Secondary pump 6 is similarly arranged on pump shaft 3, for applying the hydrodynamic pressure that regulates slideway 5.According to the present invention, now provide the logical valve 7 of 3/2-that the logical valve of 2/2-previously providing is provided, as shown according to Fig. 1, in the side 9 of exerting pressure of the logical closed secondary pump 6 of valve 7 of this 3/2-of primary importance place, and suction side 10 is connected with slideway 4 with cooling circuit 8; And as shown according to Fig. 2, at the logical valve 7 of this 3/2-of second place place, the side 9 of exerting pressure of secondary pump 6 is connected with slideway 5, and the suction side 10 of secondary pump 6 is connected with cooling circuit 8.Exerting pressure in side of secondary pump 6, arranged in addition reduction valve 11, when reaching predetermined pressure (malleation), reduction valve 11 is opened in the direction of cooling circuit 8.According to Fig. 1 and Fig. 2 in the situation that, the mode of the not involution valve that reduction valve 11 preloads with spring designs, and other mode of executions are also easily expected, they will below explained.
According to the logical valve 7 of 3/2-provided by the invention, being brake valves, is especially for example solenoid valve.3/2-leads to valve 7 electrical braking, electromagnetic braking, hydraulic braking, mechanical braking or aerobraking particularly.Secondary pump 6 can for example be designed to displacement pump, turbulence pump or side channel pump.In the case, the impeller 4 of pump and the impeller 4 ' of secondary pump 6 are preferentially incorporated in common cooling circuit 8.In addition, adjustable slideway 5 is designed to regulating sleeve, and it can be at axial direction, and the axial direction of pump shaft 3 that is parallel to impeller 4 tops of pump 2 switches.
In order to switch slideway 5, annular piston 12 is provided, its adjustable ground is arranged in annular space 13 and with slideway 5 and connects.In the case, this annular piston 12 is possible, and even can regulate slideway 5 and without otch.Annular piston 12 is common to be sealed with respect to annular space 13 on axial direction by axis Sealing (not explaining in more detail), and with respect to annular space 13, is sealing in the radial direction by radial seal 14.This also can be the axis/radial seal of combination.This radial seal 14 or axis Sealing also can omit, rather than omit reduction valve 11, make to put aside leakage between annular piston 12 and annular space 13, and this can prevent from producing malleation because of the impeller 4 ' of secondary pump 5.
More closely observe Fig. 1 and Fig. 2, can find out that the logical valve 7 of this 3/2-comprises the valve piston 16 preloading by spring 15, the spring 15 wherein with the logical valve 7 of unclamped 3/2-preloads into open position (see figure 1) valve piston 16, make, in the case, the side 9 of exerting pressure of secondary pump 6 is connected with the suction side 10 of described secondary pump 6, and the impeller 4 ' of secondary pump 6 can not apply the hydrodynamic pressure that regulates slideway 5 or annular piston 12 thus.
Cooling unit 1 according to the present invention can be realized slideway 5 with the pump in accordance with the present invention 2 especially with the logical valve 7 of 3/2-being connected and can bestly in all speed range of pump 2 switch or regulate.In the situation that the logical valve of previous 2/2-is problematic thereby particularly can provide adjusting annular piston 12 to regulate the required hydrodynamic pressure of slideway 5 in low engine speed range.For this reason, annular piston 12 builds in the mode of relative easy operating, even if make also can be easy under low power, regulates.Accordingly, in principle, also can in unloaded speed range, regulate.Yet, this requires on the other hand under high rotating speed, although bypass tube passage is opened, although according to the valve position of Fig. 1, the impeller 4 ' of secondary pump 6 produces small pressure, but this small pressure is enough to drive slideway 5 in the worst case, and slideway 5 is slided on the impeller 4 of pump 2, yet, can be by especially by means of cooling unit cooling internal-combustion engine and required cooling unfavorable herein under high rotating speed.For this reason, cooling unit 1 according to the present invention is by being used the logical valve 7 of 3/2-and reduction valve 11 to improve.
When starting, internal-combustion engine should reach its operating temperature as quickly as possible, to reduce nitric oxide production discharge, makes in the case, and cooling by cooling unit 1 is undesirable.For this reason, during this stage, logical valve 7 supposition of 3/2-are according to the position shown in Fig. 2, and the side 9 of exerting pressure of secondary pump 6 is opened towards annular piston 12 thus, and this is conducive to slideway 5 and slides on impeller 4, reduces thus the transfer rate of pump 2.The suction side 10 of the impeller 4 ' of closed secondary pump 6 is towards the connection of annular piston 12, yet, make only to contact with cooling circuit 8 herein.
Along with internal combustion engines get hot, for example, in the latter stage of cold start-up period, now the logical valve 7 of 3/2-is transferred to according to the position shown in Fig. 1, the side 9 of exerting pressure of the impeller 4 ' of secondary pump 6 is closed in the direction of annular piston 12 thus.The pressure of exerting pressure in side 9 that in this situation, reduction valve 11 is guaranteed secondary pump 6 is not higher than the pressure in cooling circuit 8 self; also guaranteed on the other hand that at least pressure from cooling circuit 8 always exists; can guarantee the fast braking of annular piston 12 thus, and the quick adjustment of slideway 5.In the case, the suction side 10 of secondary pump 6 is connected with annular piston 12, produces vacuum thus in annular space 13, thereby annular piston 12 and slideway 5 can securely be fixed.By the vacuum existing in annular space 13, opening of slideway 5 can be supported in addition, can similarly realize thus conversion circulation faster.The vacuum producing in this situation also can be used as so-called fail safe mechanism, because in this case, if for example power failure has stoped the adjusting of the logical valve 7 of 3/2-, slideway 5 is pulled because of the vacuum in annular piston 13, and the transfer rate of pump 2 improves.Depend on the vacuum amplitude producing in annular space 13, even can consider to omit spring 15 ', it switches to slideway 5 to make impeller 4 position freely.
The structure that depends on corresponding axis/radial seal 14, reduction valve 11 also can wholely omit, if for example these axis/radial seals 14 do not exist, and via passing annular space 13, the malleation that the horizontal leakage by annular piston 12 can form from the side 9 of exerting pressure of secondary pump 6 cooling circuit 8.In the case, not only reduction valve 11, and axis/radial seal 14 can additionally omit, and this has further kept following huge advantage: annular piston 12 is arranged to be easier to the mode adjustable ground of operation.By leakage, the side 9 of exerting pressure by secondary pump 6 flows in cooling circuit 8 Fluid Volume flowing back to via leakage thus.
By means of cooling unit 1 according to the present invention, especially by means of pump in accordance with the present invention 2 and the logical valve 7 of 3/2-that communicates, can be relatively simple and the effective mode of cost realize the special conversion accurately of pump 2 and the exposure of transfer rate.
